      What macOS server lacks is the RADIUS bits to do EAP.

      As far as I know you can't do EAP to LDAP.

      EAP-RADIUS works to a FreeRADIUS server, just not to macOS RADIUS as it is configured. You might be able to get it to work using a FreeRADIUS server backed by macOS LDAP for username/password but I have not tried it.

      It has been a while since I tried any of this.

        Thanks Derelict,

        In my case this is macOS Server 10.12

        Makes sense that EAP can’t do ldap.

        Is there a way to do xauth agains LDAP with Apple clients? It seems Apple clients only send user credentials as an EAP auth.

        Or if I stick with EAP - I’d love to hear if anyone knows how to (re)configure macOS server’s freeradius 2.2.x to support the MSK payload

          The problem isn't really Apple clients, it is the macOS server backend.

          I am about ready to give up on it here.

                Probably be better off posting a new thread. The forum tried to warn you. When you do post your IKEv2mobile configuration.

                  Create a new thread and I'll write there what to do
                  Show the phase 1 and phase 2 IPSEC PFSense settings there and install Apple Configurator 2 from the App Store

                    Hey,

                    @Konstanti thanks for your reply. I try to find time after the holidays to create a new topic.

                    I already installed the Apple Configurator 2.

                            After month of a working vpn my HDD was destroyed and I had no backup, I used the bad thing to turn it into something good - a clean pfSense and a perfect setup.

                            But now I have some trouble with the Encryption.

                            I currently use for phase 1 :

                            AES 256bits SHA384 DH:20

                            And for Phase 2 :

                            AES 256bits SHA384 DH:20

                            Is this secure enough?

                            When I try to follow the tutorial it doesnt work. The Hash algorithm is also grey in Apple Configurator when I chose AES-256 GCM.

                            Where is my mistake?
